c＃在表单加载时对网格进行排序

Question

我想在表单加载时对网格进行排序，但Visual Studio不喜欢我的代码。任何帮助将不胜感激！

dataGridView1.Sort(dataGridView1.Columns[0], ListSortDirection.Descending);

Answer 1

您可以在绑定数据之前对数据进行排序。例如，如果您有DataTable，则可以执行以下操作：

dataTable.DefaultView.Sort("Cola DESC");

然后绑定已排序的数据。

Answer 2

private void Form_Load(object sender, EventArgs e)
        {
            //bind u r collection to datagridview
            DataGridView1.Sort( new RowComparer( SortOrder.Ascending ) );
        }

private class RowComparer : System.Collections.IComparer
{
    private static int sortOrderModifier = 1;

    public RowComparer(SortOrder sortOrder)
    {
        if (sortOrder == SortOrder.Descending)
        {
            sortOrderModifier = -1;
        }
        else if (sortOrder == SortOrder.Ascending)
        {
            sortOrderModifier = 1;
        }
    }

    public int Compare(object x, object y)
    {
        DataGridViewRow DataGridViewRow1 = (DataGridViewRow)x;
        DataGridViewRow DataGridViewRow2 = (DataGridViewRow)y;

        // Try to sort based on the Last Name column.
        int CompareResult = System.String.Compare(
            DataGridViewRow1.Cells[1].Value.ToString(),
            DataGridViewRow2.Cells[1].Value.ToString());

        // If the Last Names are equal, sort based on the First Name.
        if ( CompareResult == 0 )
        {
            CompareResult = System.String.Compare(
                DataGridViewRow1.Cells[0].Value.ToString(),
                DataGridViewRow2.Cells[0].Value.ToString());
        }
        return CompareResult * sortOrderModifier;
    }
}

Answer 3

我通过将此行添加到BindingSource

来实现它

this.carCheckoutBindingSource.Sort = "startMiles DESC";

Answer 4

datagridview是否绑定到集合？如果是，则对集合执行排序并将已排序的集合重新绑定到datagridview

前：

collection.OrderBy(i=> i.<PropertyName>);
datagridview.DataSource = collection;

注：

我的收藏品是List。
